    GiNaC-WASM

    WebAssembly bindings for the GiNaC computer algebra system

    Demo frontend: https://daninet.github.io/ginac-wasm

    Usage

    const { initGiNaC, getFactory } = require('ginac-wasm');
    
    (async () => {
      const GiNaC = await initGiNaC('ginac-wasm/dist/ginac.wasm');
      const g = getFactory();
    
      console.log(
        GiNaC([
          // 2 * 3 = 6
          g.mul(g.numeric('2'), g.numeric('3')),
          // x + 2x = 3x
          g.add(g.symbol('x'), g.mul(g.numeric('2'), g.symbol('x'))),
          // (2*sin(x))' = 2*cos(x)
          g.diff(g.mul(g.numeric('2'), g.sin(g.symbol('x'))), g.symbol('x')),
          // internal parser of GiNaC
          g.parse('x^3 + 3*x + 1') 
        ]),
      );
    
      console.log(
        GiNaC([
          g.numeric('2'),
          g.numeric('3'),
          // reference first and second items from the array => 2*3 = 6
          g.mul(g.ref(0), g.ref(1))
        ]),
      );
    
      // besides the string output format,
      // it can also generate traversable json structures
      console.dir(
        GiNaC([
          // 2*sin(x)
          g.mul(g.numeric('2'), g.sin(g.symbol('x'))),
        ], { json: true }),
        { depth: null }
      );
    })();
